Double-Stack Filter For Ls50Tha Telescopes.

The Bandwidth Of H-Alpha Systems Can Be Reduced By So-Called “Double-Stacking”. A Smaller Bandwidth Provides Much More Contrast At The Solar Surface, Thereby Many More Details Will Become Visible.

Double-Stacking With A Bandwidth Of Only <0.55 Angstrom Is Also Possible At The Ls50Tha Telescopes. Therefore Lunt Solar Systems Has Especially Designed This Ls50C Double-Stack Filter In Compact Housing. The Filter Threads Directly Onto The Ls50Tha Telescopes.
